Patented Mar. 13, 1934 STATES PATENT OFFICE 1 Claim.

This invention relates to beverage cooling apparatus and has for an object to provide an improved construction wherein a desired cooling action is secured and yet the pipes and passageways through which the medium to be cooled passes are of easy access so as to be readily cleaned at any time.

Another object of the invention is to provide an improved cooling apparatus wherein the cooling pipes are grouped together and associated with tube plates so arranged that the fluid being cooled will pass from one pipe to another back and forth in a, restricted area, whereby a minimum amount of cooling medium may be used to secure maximum results.

A further object of the invention is to provide a beverage cooling apparatus wherein a plurality of straight pipes are used and tube plates associated therewith are arranged with grooves connecting the pipes in a certain order, the tube plates being so formed that they may be readily opened for cleaning and also for exposing the pipes to a cleaning operation.

In the accompanying drawing- Figure 1 is a view of a cooling apparatus disclosing an embodiment of the invention, the same being shown in connection with a casing adapted to contain the cooling medium;

Figure 2 is an enlarged sectional view through Figure 3 approximately on the line 22, the same illustrating the invention shown in Figure 1;

Figure 3 is a transverse sectional view through Figure 2 approximately on the line 33;

Figure 4 is a sectional view showing a development of the structure illustrated in Figure 2, and showing how the liquid passes through a tortuous passageway;

Figure 5 is a view similar to the upper part of Figure 3, but illustrating a modified construction.

In cooling carbonated water or other liquids, it is customary to provide some kind of a system of pipes arranged in a cooling medium as, for instance, ice, so that when the liquid is discharged While ordinary coiled pipes in ice would secure the desired cooling effect, it is very difficult to clean pipes arranged in this manner. In the present invention a structure has been provided whereby a desired cooling action is produced and at the same time a structure presented which may be easily and quickly cleaned.

As shown in Figure 1 of the drawing, 1 is a casing of any desired kind adapted to contain a refrigerant, for instance, ice, and the cooling apparatus 2 is arranged therein. The pipe 3 acts as an inlet pipe to the cooling apparatus 2, while pipe 4 acts as an outlet. Pipe 3, naturally, would be connected with a supply of liquid to be cooled, and pipe 4 with a valve or other device for controlling the flow of the fluid and for directing the same into the proper container. The cooling apparatus 2 is the part which embodies the invention and is shown in detail in Figures 2 and 3, and also in a schematic arrangement in Figure 4.

From Figure 4 it will be seen that the fluid flowing through pipe 3 will enter pipe 5 and pass into the passageway 6 in the header 7. From passageway 6 the fluid will move through pipe 8 into the passageway 9, and from passageway 9 it will pass into and through pipe 10 so as to discharge into passageway 11. From passageway 11 the liquid flows through pipe 12 into passageway 13 and thence into and through pipe 14. From pipe 14 the fluid discharges into the outlet pipe 4. All of the pipes and tube plates comprising the entire apparatus are preferably covered with ice, or a combination of ice and water, or other cooling medium. Consequently the fluid flowing in the tortuous passageway as just described will become chilled or cooled to the desired extent before it is discharged out through outlet pipe 4.

The respective headers 7 and 7 are the same in construction except for the arrangement of the inlet and outlet pipes. A description of one header, therefore, will apply to both. As shown in Figure 2, header 7 is provided with a tube plate 15 and with a cover plate 16. The plate 15 is formed with the passageways 6 and 11. The respective pipes 5, 8, 10, 12 and 14 are connected to the plate 15 by welding or soldering, as at 1'7, so that the pipes are practically integral with the plate 15 of the header 7, and similarly with the plate of the header '7'. The cover plate 16 is provided with an offset arrangement 18 which fits tightly against the top of the plate 15 within the shoulder 19, while the various ears 20 are pressed toward ears 21 of plate 15 by the rods or bolts 22. It will be noted that the rods or bolts 22 hold the respective plates 16 and 16' against plates 15 and 15. If desired, a washer or other suitable gasket could be provided so as to prevent any leakage from the passageways 6 and 11 or 9 and 13.

When it is desired to clean the pipes, the bolts 22 are removed, and plates 16 and 16' are removed. This will expose the various passageways and also the various pipes so that they may be readily cleaned. After this has been done the plates 16 and 16' are replaced and the device is ready for operation.

In Figure 5 a slightly modified structure is shown which is identical with that shown in Figures 2 and 3 except that plate 23 is provided with apertures through which the various pipes discharge, while the plate 24 has the various passageways 6 and 11. It will thus be seen that in this form of the invention the respective headers are arranged so that the passageways will be in the removable plates, while in the form shown in Figure 2 the passageways are arranged in the fixed plates. In both forms of the invention the various plates are readily cleaned and the pipes may also be cleaned readily as easy access may be had to the same. It will be noted that all of the pipes are straight and, consequently, a cleaning swab may be forced through any or all of the pipes with ease.

I claim:-

A beverage cooling apparatus comprising a pair of tube plates, a plurality of pipes permanently connecting said tube plates, one of said pipes being adapted to be connected with the inlet pipe and another of the pipes adapted to be connected with the outlet pipe, each of said tube plates being provided with passageways connecting cer tain pipes, said passageways being arranged so that there will be a continuous tortuous passageway from the inlet pipe to the outlet pipe, each of the tube plates being rigidly connected with the respective pipes, each of said tube plates having an annular upstanding portion at the periphery, and a removable cover plate for each tube plate for covering the passageways therein, each cover plate having a flange fitting over said annular upstanding portion and a depending portion fitting within said annular upstanding portion so as to present one wall for the passageways in said tube plates, and a plurality of bolts extending through the flanges of both of said cover plates and also through the upstanding portions of both of said tube plates for firmly clamping said cover plates in position.

ANTON LANDGREBE.
